To all whom it may concern United States, residing at Port Jefferson Station, Long Island, in the county of Suffolk, State of New York, have invented cer tain new and useful Improvements in Collapsible Bed-Springs; and we do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled inthe art to which it appertains to make and use the same.

This invention relates .to a collapsible bed spring. 7

An object of the invention resides in the provision of a device of this character which may be readily disassembled and the parts conveniently packed for shipping. 7

A further object of the inventionresides in so constructing the device that the spring portion may be subjected to various degrees of tension when the device is assembled.

With these and other objects in view, such as will appear as the description progresses,

' the invention comprises the combination and arrangement of parts as set forth in and falling within the scope of the appended claim.

Referring to the drawing: Figure 1 is a side elevation of the device. Fig. 2 is a bot tom plan view thereof. Fig. 3 is a vertical sectional view on line 33 of Fig. 1. Fig. 4 is a longitudinal vertical sectional view through the push bars.

Referring to the drawing wherein likeparts are indicated by like characters throughout the several views :-In the embodiment of the invention shown in the drawing we'have provided a frame which consists of end bars 1 having reinforcing strips 2 secured thereto, the end bars being of greater widths than the reinforcing strips. Secured to these end bars 1 and extending between the same and the reinforcing strips is a spring member 3.

In order that the end bars may be held in their proper positions, rigidly, and the ed in the holes 4 are push bars 6, the ends of which are adjustably secured together by "theinse'rtion of'a hancnes WIN and ALoNzo R. SH TE, citizens ofthe' *on'th'e push bars 6 are collars 9 to which are that numerous changes may be turn buckles 'Z having openings 8 therein for siiuabl mounted .1 are provided with sockets 14 for engaging the end of the bed so as to hold the device in place.

In assembling the device the spring mem her 3 is laid out flat with the end bars attached to each end thereof. The push bars with the turn buckles between them are inserted in the holes 4, the ends of the brace rods 10 are inserted in the holes 5 and the nuts 11 engaged therewith. The turn buckles are then operated to force the push bars apart and consequently stretch the spring member. When the proper tension is attained the nuts 13 may be adjusted to draw the brace rods 10 so that the end bars will be rigidly held in their proper positions.

It is to be noted that after the springs have been stretched by the push bars that the end bars 1 may be drawn into such posito the pushbars and it will be necessary to force these end bars into this position be cause of the fact that the pivotal points lie in alinement with the push bars andfurther because of the fact that the force which is applied to the end bars is applied by the springs and above the pivotal point. It is the presence of the adjusting nuts 13 that permits the easy assembly of the parts and permits the brace memberslO to be drawn into such positions that the push bars will be maintained in the holes 4 and prevented from displacement therefrom.

It will thus be seen that we have provided a very simple collapsible bed spring which may be easily assembled or disassembled and when assembled Wlll be rigid and the spring member under the proper tension.

While we have illustrated and described a particular embodiment of our invention we have merely done so for the sake of convenience and do not wish to be limited to that particular embodiment as it is obvious made within the details of construction thereof without V :exten ing between the end bars adjacentto in any way departing from the spiritof the the lower edgesthereof and adjustably coninvention or exceeding the scope of the ap-, nected to the push bars and means for securpended claim.
